Database

I’ve just returned from my honeymoon in Venice with the wonderful Tim Gorman, but before we enjoyed our week in this picturesque city, we spent a week doing joint keynotes and two sessions each on our own tech topics at these two incredible conferences in neighboring countries.

Introduction

A long time has gone since my last blog post on SCN in March 2014, but i was quite busy with Oracle RAC implementations and troubleshooting performance issues in the last month. It was a quite interesting time for me and i have learned a lot of new stuff about Oracle 12c and so in consequence this is just a tiny blog post about a new diagnostic event called "wait_event[]", which was introduced with Oracle 12c R1 (12.1.0.1). Oracle has re-engineered its kernel diagnostics & tracing infrastructure with Oracle 11g, which allows you to be much more detailed and extensive by tracing and dumping diagnostic / low level (internals) information. Please check the reference section for more detailed information about that "new" kernel diagnostics & tracing infrastructure, if you have never heard of it until yet.

I’m doing some sessions on analytic functions in some upcoming conferences and I thought I should look at this stuff. I’m not really going to include much, if anything, about it as my sessions are focussed on beginners and I don’t really want to scare people off. The idea is to ease people in gently, then let them scare themselves once they are hooked on analytics. I’m thinking about Hooked on Monkey Fonics now…

Over the years I’ve written loads of stuff about consuming and publishing web services directly from the database. I’ve been doing quite a bit of this at work recently and I realised how difficult it is to find all the pieces, since they are spread across multiple articles, spanning multiple database versions. In an attempt to give a single point of entry I’ve written this very brief article.

Just a quick note to point out that the October PSU was just released. The database has a few more vulnerabilities than usual (31), but they are mostly related to Java and the high CVSS score of 9 only applies to people running Oracle on windows. (On other operating systems, the highest score is 6.5.)

I spent a bit of time at OpenWorld looking at the JSON support in Oracle Database 12c. I started to write some stuff about it on the plane home and I spent the last two mornings finishing it off. You can see the results here.

I’ve tried to keep it light, since the documentation does a pretty good job at explaining all the variations of the syntax. I’ve also avoided trying to teach people about JSON itself. There is loads of stuff about that on the net already.

For the most part I think the JSON support looks pretty cool. During the process of writing the articles I did notice a few of things that I thought might confuse.
